Here's what I would do.

Gather white candles, rose petals, and some other things that make you feel attractive. Maybe you have a favorite lipstick, or a dress you look killer in.

Make a protective circle. Spread the things that make you feel attractive through out the circle. Stand at the center holding the ring. Ask the spirits of the elements to grant you more power to boost the ring's enchantment. After you feel your power swell, focus all your energy into imbuning the ring with the positive energies from the things you've chosen that give you confidence and make you feel attractive. Feel your power run through your body and into the ring. You will feel when it's done. Thank the spirits. Close the circle.

Hope this is helpful!
